SimGRACE: A Simple Framework for Graph Contrastive Learning without Data Augmentation

PyTorch implementation for SimGRACE: A Simple Framework for Graph Contrastive Learning without Data Augmentation accepted by The Web Conference 2022 (WWW 2022).

Overview

In this repository, we provide the codes of SimGRACE to evaluate its performances in terms of generalizability (unsupervised & semi-supervised learning), transferability (transfer learning) and robustness (adversarial robustness).

Dataset download
